GASTROPODA. 17 



Locality. — Not rare at Minbu and Yenangyat. 



Remarks* — The peculiar bead-like ornaments distinguish this 

 species easily even in fragments. As regards the arrangement of the 

 sculpture, this species seems to be closely related to the living Clancu- 

 lus scadrosus, Phil., from Bombay, but I do not think that both are 

 identical.

The specimens which I collected are not sufficiently well preserved 

 to permit a closer description of this species, which, owing to its 

 relationship with species already known, seems doubtfully indepen- 

 dent. However, the specimens from Burma exhibit such characters 

 that it appears compulsory to identify it with the Indian species 

 whatever the specific value of that form may be. 



The shell is circular, depressed conical above, slightly convex 

 below. The whorls are angular at the periphery, the suture very 

 indistinct owing to the revolving furrows which mark the upper part 

 of the whorls. Umbilicus, narrow, less than one-third of the total 

 diameter of the shell, strongly crenulated. The sculpture consists, 

 on the upper part of the whorls, of four sharply marked revolving 

 furrows, of which the 1st and the 3rd, counting from the suture down- 

 wards, are deeper than the 2nd and the 4th. These are crossed by fine 

 equidistant transverse striae, which thus produce a kind of granular 

 sculpture just below the suture. On the lower side there are also four 

 revolving furrows,but here two of them are quite close to the peri- 

 phery, while the other two are close to the umbilical edge. Short but 

 deep furrows radiate from the umbilical edge and produce a granular 

 sculpture on inner part, while the peripheral part remains smooth* 

 Locality .—Minbu and Yenangyat, but rather rare.
